Guidelines for queuing method calls using Vue.js

Is there a way to invoke a method using a queue system? Imagine having a method that makes API calls and can only handle 3 calls at once. If more than 3 calls are made from a component, the remaining ones should wait until one call finishes before proceeding.

Just to clarify, this is not about looping API calls, but rather calling them based on user actions in a real project.

for (let i = 0; i < 9; i++) {
  doSomething(i)
}

doSomething(param){
//call api
}

The goal is to execute doSomething for values 0 - 9, but ensuring that only the first 3 calls trigger API requests while the rest will be queued and wait for an available slot.

Answer №1

Consider utilizing the power of Promises and async functions in your code implementation.

Here is a simple example to guide you:

for (let i = 0; i < 9; i++) {
  performTask(i)
}

async function performTask(param) {
  if (param < 3) {
    const result = await fetchData();
    console.log(result);
  } else {
    const result = await fetchData();
    console.log(result);
  }
}

async function fetchData() {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve('data fetched successfully')
    }, 2000)
  })
}
